Both are ATX mid towers, offer cable management and support up to 160mm tall CPU coolers. They also both have good Newegg ratings.

Just remember that cases are cheaper than others for a reason. I haven't had any hands on experience with NZXT, but have good experience with Antec and Corsair. Also make sure you look at maximum GPU length clearance, since the Antec One looks like it wouldn't fit many newer cards (at least for the Radeon ones).
